4. The vehicle roof support pillar assembly of claim 1 wherein the first support pillar includes a first flange extending in a fore longitudinal direction from the first hollow body and located at a first upper portion of the first hollow body, and wherein the second support pillar includes a second flange extending in an aft longitudinal direction from the second hollow body and located at a second upper portion of the second hollow body.
5. The vehicle roof support pillar assembly of claim 1 further comprising a rocker panel attachment coupled to a first and second lower portion of the first and second support pillars, and comprising a roof rail attachment coupled to a first and second upper portion of the first and second support pillars.
6. The vehicle roof support pillar assembly of claim 1 further comprising a pocket located partly between the first and second support pillars at a respective first and second lower portion of the first and second hollow bodies, the pocket sized to receive a seat belt retractor.
7. The vehicle roof support pillar assembly of claim 1 further comprising a noncontact region located at a first and second lower portion of the first and second hollow bodies and formed in part by the first and second side surfaces being spaced away from each other.
8. The vehicle roof support pillar assembly of claim 1 wherein the first support pillar has a first lower free end that tapers closed and that is wider in a longitudinal direction than a first middle portion of the first support pillar, and wherein the second support pillar has a second lower free end that tapers closed and that is wider in a longitudinal direction than a second middle portion of the second support pillar.
9. The vehicle roof support pillar assembly of claim 1 wherein the first support pillar has a first upper free end that is open, and wherein the second support pillar has a second upper free end that is open.
10. The vehicle roof support pillar assembly of claim 1 wherein the first hollow body is formed by a hydroforming process and the second hollow body is formed by a hydroforming process.
11. An auxiliary vehicle roof support pillar assembly, comprising:
a first auxiliary support pillar having a first hollow body formed from a tubular blank of material and constructed to extend vertically along at least a portion of a primary vehicle roof support pillar and constructed to attach to the primary vehicle roof support pillar; and
a second auxiliary support pillar having a second hollow body formed from a tubular blank of material and constructed to extend vertically along the at least a portion of the primary vehicle roof support pillar next to the first hollow body, and constructed to attach to the primary vehicle roof support pillar so that the first and second auxiliary support pillars reinforce the primary vehicle roof support pillar, and wherein the second auxiliary support pillar is separate from and not directly connected to the first auxiliary support pillar along at least a portion of the length of the second auxiliary support pillar to define a noncontact region having a gap that extends between the first auxiliary support pillar and the second auxiliary support pillar.
12. The auxiliary vehicle roof support pillar assembly of claim 11 wherein the first and second hollow bodies are formed by a hydroforming process.
13. The auxiliary vehicle roof support pillar assembly of claim 11 wherein the first and second hollow bodies are coextensive in vertical length along the at least a portion of the primary vehicle roof support pillar.
14. The auxiliary vehicle roof support pillar assembly of claim 11 wherein the first hollow body has a first side surface and the second hollow body has a second side surface substantially confronting the first side surface, the first and second side surfaces contacting each other along at least a portion of their respective vertical extents to form a contact region therebetween.
15. The auxiliary vehicle roof support pillar assembly of claim 11 wherein the first hollow body has a first side surface and the second hollow body has a second side surface substantially confronting the first side surface, the first and second side surfaces being spaced away from each other and not contacting each other and not directly connected to each other along at least a portion of their respective vertical extents to form a noncontact region therebetween.
16. The auxiliary vehicle roof support pillar assembly of claim 11 further comprising a first bracket, wherein the first and second hollow bodies are attached to the primary vehicle roof support pillar by way of the first bracket.
17. The auxiliary vehicle roof support pillar assembly of claim 16 further comprising a second bracket, wherein the first and second hollow bodies are attached to the primary vehicle roof support pillar by way of the second bracket.
18. The auxiliary vehicle roof support pillar assembly of claim 11 wherein the first and second hollow bodies are attached directly to the primary vehicle roof support pillar by way of at least one weld.
19. The auxiliary vehicle roof support pillar assembly of claim 11 wherein, when assembled, the auxiliary vehicle roof support pillar assembly is located at an upper portion of the primary vehicle roof support pillar.
20. A vehicle roof support pillar assembly, comprising:
a primary vehicle roof support pillar adapted to extend between a vehicle roof rail and a vehicle rocker panel; and
an auxiliary vehicle roof support pillar assembly including a first auxiliary support pillar and a second auxiliary support pillar, the first auxiliary support pillar having a first hollow body extending vertically along at least a portion of the primary vehicle roof support pillar, the second auxiliary support pillar having a second hollow body that is separate from the first auxiliary support pillar and extends vertically along the at least a portion of the primary vehicle roof support pillar next to the first hollow body, the first and second auxiliary support pillars reinforcing the primary vehicle roof support pillar.
